Problems solved by technology

[0004] The water flow has the problem of spiral and flocculation. The water flow enters the water inlet channel and directly impacts the impeller, which makes the impeller bear a large impact force. The impeller has problems of shaking and unstable rotation, which reduces the stability of the canned pump.
At the same time, in the shielded pump with this structure, the central axis of the water inlet channel and the central axis of the water outlet channel overlap, but the position of the impeller is obviously above the central axis of the water inlet channel and the water outlet channel, that is, the water at the impeller is in contact with the water inlet channel and the water outlet channel. The water in the water outlet channel has a large vertical height deviation, which makes the impact force of the water flow on the pump head large and reduces the stability of the canned pump

Abstract

The invention provides a shield pump, and belongs to the technical field of pumps. The problem that an existing pump is poor in stability is solved. The shield pump comprises a pump head, one end of the pump head is provided with a water inlet channel, the other end of the pump head is provided with a water outlet channel, a water passing channel communicated with the water inlet channel and the water outlet channel is arranged in the pump head, an impeller is arranged in the water passing channel, a water inlet is formed in the middle of the bottom of the impeller, and a drainage support is fixedly connected in the water passing channel and located under the center of the impeller. The central axis of the water inlet channel, the central axis of the water outlet channel and the center of the impeller blade are located on the same straight line. The shield pump has the advantage of good stability.

Description

Technical field [0001] The present invention belongs to the field of pump technology and involves a shielding pump. Background technique [0002] The shielding pump is a leakless pump consisting of a shielded motor and pump. The shielding pump is widely used in many occasions in the fields of petrochemical, defense military industry, aerospace, air -conditioning cooling, cooling liquid cooling system, pharmaceutical food, atomic energy and other fields. Increased pressure on drinking water. [0003] Existing shielding pumps, such as Chinese patent documents, disclosed a standard water standard circulating output shielding pump [Application number: 201920636022.5; authorized announcement number: CN209800292U], this shield pump includes pump heads, pumps, stator, rotor and impeller wheels Between the pump head and the pump body, the card slot is formed at the connection, and the edge card of the shield is located in the card slot. Tighten the fixation, the bearing is installed in t...
